Why does my 1989 Isuzu Trooper 4 cylinder idles rough when first started and goes dead several times After it gets warm it idles a little better Any ideas?
I am not a pro, but mine broke the locating pin on the cam
pully, which altered the cam timing. Luckily the valves do not
touch the pistons! The engine was pulled and ready for rebuild when
it was found. I rebuilt it anyway.
